SECONDARY BATTERY.

SPECIFICATION forming part of Letters Patent No. 654,520, dated July 24, 1900.

Application filed October 2, 1899. Serial No. 732,355. (No model.)

To @ZZ 'LI/71,0711, it may concern:

Be it known that I, CLYDE J. COLEMAN, a citizen of the United States, aud a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in SecondaryBatteries; and I do hereby declare the following to be a" full,

clear, and eXact description of the same, reference beinghad to the accompanyingdrawings, Io forming a part of this specification.

The present invention relates to that type of secondary batteries in which the active material is inclosed within perforated casings of conductive material, an example of which I5 forms the subject-matter of my application for Letters Patent liled August 3, 1899, Serial No. 726,014.

The object of the present improvement is to provide a durable and efficient connecting 2o means between a series of tubular holders or casings and a connecting bar or strip to constitute an electrode for secondary batteries, all as will hereinafter morel fully appear, and be more particularly pointed out inthe claims. 2 5 In the accompanying drawings, illustrative of the present invention, Figure l is a fragmentary longitudinal section of a secondarybattery electrode embodying the present invention; Fig. 2, a similar transverse section 3o of a pair of such electrodes; Fig. 3, a detail longitudinal section of the connecting bar or strip of the present improvement.

Similar numerals of reference indicate like parts in the different views.

ondary-battery electrode of the present invention will comprise a series of elongated tubular casings or holders 1, formed of perforated lead tubing or other like conducting material 4o and arrangedin parallel and separated relation, with their upper ends connected together by means of a conducting strip or bar 2, the arrangement being substantially the same as that set forth in my aforesaid former application, Serial No. 726,014.

, The first part of the present improvement involves the formation Cf the connecting strip or bar 2 with a series of vertically-extendin g necks or flanges 3 of a diameter correspond- 5o ing to that of the upper ends of the lseries of tubular 'casiugs or holders 1 and adapted to fit over such ends and afford an extended sura face'contact between the parts to aord both a substantial mechanical connection and a maximum conductive union between the part's,and which conductive union maybe still further increased by a fusion together of the upper ends of the flanges 3 and the tubular casings I, as set forth in my former application,'Serial No. 726,014, 6o

Another part ofthe present improvement involves the formation of the connecting strip or barwith a wide horizontal portion 4, in l which the necks or anges 3, heretofore described,"are formed, and. with longitudinal iianges 5 at each side of the horizontal portion- 4 to adord lightness aud rigidity to the connecting strips or bars.

The series of tubular and perforated casin gs or holders 1 arefilled with loose active mate- 7o rial, such as oxid of lead, to constitute the completed battery-electrodes, as usual in the present type of secondary batteries.`

Having thus fully described mysaid invention,what I claim as new, and desire to secure by Letters Patent, is@ w Y 1. In a secondary battery, the combination of a perforated conducting-Casin g forcontain'- ing the active material, and a connecting strip or bar having an opening with a thin verti- Se cally-extending flange or neck around said opening receiving the upper end of such casing, and adapted to afford a convenient means for effecting a fused joint between the parts, substantially as set forth.

2. In a secondary battery, the combination of a series of perforated conducting-casings for containing the active material, and a connecting strip or bar,corn1non to the series,and having an opening with a series of thin verti- 9o cally-extending flanges or necks around said opening receiving the upper ends of such casings, and adapted to afford a convenient means for eecting a fused joint bet-weenthe parts, substantially as set forth.

3. In a secondary battery, the combinationof a perforated conducting-casing forcontaining the active material, and a connecting strip or bar having an opening with a horizontal plate portion, longitudinal side fianges, and Ico of suoli casing and adapted to afford a convenient means for effecting a fused joint between the parts, substantially as set forth.

4. In a secondary battery, the combination of'a series of perforated conduoting-casings for containing the active material, and a con- :meeting strip or bar common to the series, and formed with a horizontal plate portion, longitudinal side flanges, and a series of thin vertiio cally-extending flanges or necks receiving the upper ends of such casings, and adapted to afford a convenient means for effecting a fused joint between the parts, substantially as set forth.

In testimony whereof Witness my hand this 15 2d day of September, 1899. Y

CLYDE J. COLEMAN. In presence of- BOBERT BURNS, HENRY A. NOTT.
